It has become necessary to address an aging transmission line which has been in operation since 1959 between our Carolina Substation and the South Justice Branch Junction in Halifax County, North Carolina. This approximately 17.7-mile overhead electric transmission line was originally constructed on wooden H-frame and steel lattice structures. We are rebuilding the entire 115 kV line and parts of the double-circuit 230 kV line in the existing easement using structures similar in appearance and height. All replacement structures will be constructed of brown, weathering steel; new single-circuit structures will be H-frames, and new double-circuit structures will be monopoles. No new right of way is needed.


  • Maintains current right of way
  • New structures located in the same general location as existing structures
  • Complies with mandatory standards to ensure safety, reliability and to meet future needs
  • Minimizes impact to the community and environment
  • Replaces aging infrastructure

  • LATE 2023: Preconstruction activities, including access installation
  • JANUARY 2024 - DECEMBER 2025: Single-circuit rebuild from Carolina Substation to South Justice Branch Junction
  • APRIL – JUNE 2024: Double-circuit rebuild in Roanoke Rapids
  • SEPTEMBER – NOVEMBER 2024: Double-circuit line work at the I-95 crossing
  • 2026: Continue other transmission line rebuilds in this corridor and begin restoration of right of way

Project Outcome

Corten Monopole

The double-circuit replacement structures are brown, weathering steel monopoles.

Original Average Height: 115 feet. New Average Height: 120 feet.

White Proposed Tangent

The single-circuit replacement structures are brown, weathering steel H-frames.

Original Average Height: 60 feet. New Average Height: 70 feet.

Most replacements look similar and will be located close to the original structures.
